α-Conotoxins, a family of small peptides from the venoms of the Conus marine molluscs, are selective, snake α-neurotoxin-competitive antagonists of the nicotinic acetylcholine receptor. A new α-conotoxin, SIA, has been purified, sequenced, and synthesized. Crosslinking with bivalent reagents and photoaffinity labeling of the acetylcholine receptor with α-conotoxin yield covalent adducts. Surprisingly, crosslinking to other subunits is considerably more efficient than to the α subunit. The relative efficiency of photoactivatable crosslinking to different subunits of the receptor is a function of placement of the photoactivatable group on the toxin. Since the structures of α-conotoxins can be solved by 2D NMR (Pardi, A. et al., 1989 and Kobayashi, Y. et al., 1989) this family of toxins should provide a set of new ligands for probing the acetylcholine receptor with considerable precision.
